Afternoon sks fans....
General question that has been bantered around in the past and recently on another board...just wanted to see what current thoughts with folks here are on Russian sks bayos for my clarification.
Are there any original/not modified, refurbed, replaced bayos that were blued on the original rifle or where all bayos issued in the white and only blued after replacement or refurb?
1949 Russian sks w the spiker comes to mind, and it was only after that first production that bayos were installed "in the white".
Thoughts?
For all intents and purposes, from 1956-1958 Jianshe was the third Soviet sks facility-- Soviet machinery and spare parts from Russia, soviet design, and soviet techs and managers overseeing all aspects of production. Mao's intent was to industrialize and modernize as quickly as possible. There was no time to waste on refining or rethinking the Soviet design or production method. The Soviets simply made all of the equipment for a new sks production line, and installed it at Jianshe along with the Soviet techs and advisors. As a result, the early years of Chinese production were a cut and paste copy of the Soviet method.
Other than the catalpa hardwood stocks, the early Chinese guns are exact copies of the final Soviet sks design. If the Chinese SKS bear no evidence of golden coating or bluing, why would we expect the Soviet bayos to be any different?
The honest answer is that nobody knows.
There are several camps though, each with solid arguments and questionable reaches.
One camp considers a golden bayo to be the de facto way every bayonet was issued. Many of the the 'as-issued' Russian SKS45s I have in the database have these types of bayos installed, but definitely not all of them are golden. The question in my mind has always been what level of refurbishment did these seemingly 'as-issued' guns actually receive? Most certainly disassembly and cleaning at a minimum. Buttplates also show extensive evidence of cleanup, painting or removal of paint. The stocks themselves exhibit interesting characteristics of a very light refinish of the shellac, with multiple brush marks and shellac over stamped characters that clearly indicated the coating happened sometime after the original shellac was applied. Knowing this, I don't think it is a stretch to think that original bayonets were pulled and coated with the chromate conversion coating for additional corrosion protection during long term storage.
Boris's argument that we simply don't see the coating on Chinese SKS bayonets in the '56 to '60 time period is certainly a valid observation. Of course one might argue that the Chinese simply do not have near the amount of 'as-issued' carbines from this time period as the Russians do and a huge majority of our examples are refubished imports.
As for blued and black painted Russian bayos. I think many camps will argue that they are the result of refurbishment of some kind and not the original finish. I've heard some argue that original bayos right after the switch from spike to blade in the '50 production model *could* have been blued before the Russians transitioned to bright or matte silver blades, but since there are so few 'as-issued' '50's out there, it's pretty hard to verify. Blued bayos appears on refurbs of all years, so it appears that either the '50's stock of blued bayos scattered to the 4 winds during refurb (if they were originally all blued on '50 carbines), or each refurb shop blued bayos during refurbishment as they saw fit.
I had definite leanings in one direction long ago, changed my mind, changed it again, and finally said "to heck with it, I don't know". It would be nice to solidly answer the question, but, aside from new info out of Russia (unlikely anytime soon, if ever) I honestly don't know that it can be done.

Regarding early Chinese blade bayonets, I've never seen one with a golden coating in any of the propaganda posters. Granted, these aren't photos, but the color depiction in every graphic I've seen portrays only shiny steel:

Admittedly, my theory is entirely circumstantial. But there's a lot to it.
For example. After 1955, the Soviets were producing the AK47 in large enough quantities that the many Soviet SKS could be relegated to long term storage, conspicuously sans heavy cosmoline-- at least as evidenced in the US imports. It makes sense that bluing and chromate coatings were added as anti-corrosion measures in the absence of a protective coating of storage grease.
The obvious question that follows is: Why the variance in bayo appearance-- i.e. gold, blued, or nothing at all?
My best guess is that this either had to do with location-- i.e. where and how the rifles were stored or how regularly they were subjected to inspection at a given storage location. Or both.
That's a good observation Boris.
Here is one of the nicest '58 SKS45's I can find in my files:

vs. one of the nicest year 3(1958) Chinese type 56's I can find:

Not sure it proves anything necessarily, but it definitely doesn't disprove your hypothesis. It could be the storage method (heavy grease vs some other preservative) might be responsible for something like this (needing a golden bayo vs having a bright/matte silver bayo). It could also be that the storage method (during the cleaning of the preservative from the carbine) is directly responsible for the removal of the golden chromate coating too (highly unlikely as a chromate conversion coating is relatively easy to scratch/damage but really tough to get completly off!)
Chinese aid to Albania started in 1960 when Moscow cut ties with Peiking and Tirana. As far as I know none of the early type56's from the Albanian imports bear any hint of chromate or original bluing on the blades.
And though the Soviet sneaks represent a much smaller quantity, I've not seen one yet with a golden or blued bayo. Just another observation in a confluence of circumstantial evidence.
Here's my all matching 1958 from the Albanian caches. Note the late serial tally paired with bottom sling mount .

(3) Bayonets on late (e.g. 1958) Russian SKS were not leftovers from earlier production?
At least, I am not convinced that all parts of Russian SKS were made completely 'in-house'. And I don't even fully believe that Russian letter guns were actually made at Tula.

Soviet chemist, Mikhail Klochko, served as one of the technical advisors. From his own account, not only were the Chinese importing whole production lines and facilities from the USSR, they also had little to no capacity to produce the necessary spare parts to keep those new production lines running. If a given piece of equipment broke down, it didn't go back on line until the replacement parts came from Russia.
Here's a link to his article from the summer 1971 issue of
International Journal:
https://www.jstor.org/stable/40201404?read-now=1&refreqid=excelsior%3Acb6911263c5ea88ed57fcae47d6d67d8&seq=11#page_scan_tab_contents
In June of 1960, when the Kremlin abruptly withdrew
all Soviet advisors in China, they also cut off the supply of all those critical replacement parts. And those facilities that were dependent on Soviet supply, saw either significant slowdowns in production, or were force to go off line completely.
From collected serial data, it strikes me as more than coincidental (conspicuous, even) that barely 300,000 rifles can be accounted for during the
three year period from 1959 thru 1961. That's a 60% (-ish) reduction in expected yearly production totals. Whether production slowed during this period, or there was a prolonged stoppage, this drastic plunge in production at this specific point in time suggests that sks production was one of those new production lines that was still heavily dependent on Soviet resupply for continued operation.
Admittedly, this is not in any way definitive proof that the soviets were supplying bayonets. But it is a significant intersection of circumstances.
In another way, I'm not sure it really matters where the bayonets came from. If there was a standard being followed it was a Soviet standard and
not Chinese one-- at least not in the first two or possibly three years of production-- (thus, the first deviation from the soviet design is seen in 1958 with the relocation of the stock swivel). And that standard was bland, undifferentiated, uniformity among enlisted men and the kit and equipment they were issued.
Quote(2) there weren't more than one supplier in Russia that made bayonets for Russian SKS?
It seems very possible that blade bayonets could have come from multiple suppliers, and similar would be just as possible for other components. But I think there was still one standard. Otherwise, we could expect to see similar variations in other "original" parts-- particularly bolts and carriers.
Quote(3) Bayonets on late (e.g. 1958) Russian SKS were not leftovers from earlier production?
At least, I am not convinced that all parts of Russian SKS were made completely 'in-house'. And I don't even fully believe that Russian letter guns were actually made at Tula.
If there is a single standard, outsourcing component production doesn't really matter. At a certain level-- everything had to be the same. Differences in knurling on bayonet handles and safety levers are insignificant. But gold or blued bayonets are a significant alteration to the overall aesthetic. And variation (read: individuality) is directly opposed to the type of bland homogeneity, and sanitized de-individualization imposed at enlisted levels of military service.
Here is a bayonet description from declassified CIA document regarding 156 new SKS45's issued to a Red Army Communications Battalion staionined in the Soviet zone in occupied Austria. The details are second hand and come from eyewitness accounts.
The bayonets are described as either only chrome plated or having rough, flat "not shiny" finish. There is no mention of gold chromate or black/blue bayonet finish.

Here's a link to the full declassified CIA document:
https://www.cia.gov/readingroom/docs/CIA-RDP82-00046R000500020007-7.pdf
For reasons of transparency I must note that there are various inconsistencies/ inaccuracies in the description of the new 7.62 carbine, but these are mostly regarding function and design which can be expected as the account is from an Austrian eyewitness and not from one of the Soviet soldiers to whom the rifles were issued. As well the eyewitness account is from March 1954, but the CIA report is filed a year later in April 1955-- so details could have been misremembered when recounted to CIA operatives.
It is also a small sample, only 156 rifles.

Interesting thread that I was not aware of.
If we consider pcke2000's suggestion that production of various components may have been outsourced to smaller facilities, it's very likely that there are similar dimensional variations in any randomly selected batch of blade bayonets. I believe similar variation has been measured in barrel diameters, thus the different number sizing (1,2, or 3) seen on the front of the front site posts.

In the SKS world, "Non refurb" 1950's are about as rare as they come. But they do exist:
Here's one from shared by CARBINE nearly a decade ago-- with photos (note the uncoated bayonet)
https://sks-files.com/index.php?topic=86.msg8926#msg8926
And here's another discusscion thread of a potential 1950 non-refurb
with a Chromate gold bayo. Sadly there are not photos, only links to the closed auction on Gunbroker.
https://sks-files.com/index.php?topic=5332.0
Here's a thread post (with photos) of a 1950 potential non-refurb with a partial gold chromate coating:

Here's another 1950 with good photos. Hits all the buttons for a potential "straight-to-storage" carbine-- bare blade, no gold or black bayo:

Here's a 1950 with the black/blued/perma-blued bayonet. Owner suggests non-refurb-- which isn't impossible, but the barely visible stock serial, date and arsenal mark indicate significant amount of post production use or maintenance handiwork:
https://www.gunboards.com/threads/another-non-refurb-1950-sks-but-black-blade-bayo.1178384/#lg=thread-1178384&slide=12
I've put a lot of thought and examination into this subject over the last few years. Here are some of the things I've noted that suggest to me that bare white steel was the standard for original Soviet sks bayonets.
Blued/Perma-blued bayonets have long been claimed to be an indication of refurbishment because they are overwhelmingly found with mis-aligned staking marks. ( I agree that the stake marks are a good indication that the bayonets were removed post manufacture-- but this is not in any way definitive proof of refurbishment). What seems far more likely in my opinion, is that the stake marks are misaligned because the bayonets had to be removed in order to apply the coating--- post manufacture.
Other than the Yugo M59's, all sks variants exhibit bare/in-the-white blade bayonets: Romania, East Germany, N. Vietnam, Korea, and China. Yugoslavia, with limited access to chromium used a different type of metal composition for the M59. Though, I am not certain what gives the M59 bayonet it's distinctive dark gray coloring.
1950's AK47 have blade bayonets: Not gold or blued but bare, white steel.
Chinese small arms of the 1950's are exact copies of Soviet weapons of the era. So much so that parts are interchangeable. The Type 51 tokarev, Type 53 mosin, Type56ak, Type56 sks, Type56 RPD, and the Type59 Makarov-- are all exact mechanical and aesthetic copies of contemporary Soviet firearms. Indistinguishable beyond arsenal markings and serialization fonts and style. and produced during Mao's 1st and 2nd Five Year plans on Soviet made machinery, under direct supervision and training by Soviet techs / advisors. If the Soviet production model was the standard was for blued or gold sks bayonets, why would the Chinese all of a sudden deviate from that standard when every other Chinese small arm of the period was an aesthetic and mechanical copy of a Soviet design?
The Gold bayonets are often claimed to be original because the staking are commonly still aligned. The explanation being that the stake marks indicate that the bayonet has not been removed and thus the gold bayonet must be original. But this argument overlooks the very likely possibility that the gold or chromate application did not require the bayonet to be removed at all. The many gold bayonets I've seen over the years strike me more as having been left in place and simply dipped in a coating solution.
None of this is definitive, of course. But it makes a pretty solid case that in-the-white was the standard for Soviet sks manufacture-- and why every other blade variant exhibits bare steel.
Hundreds of thousands of Chinese blade carbines have come into the US in the last decade and I'm not aware of even one that was imported to the US with a gold or blued bayonet.
Edit:
It has always struck me as highly irregular to have multiple production standards for a stop gap rifle that was destined long term storage or rear guard issue even before it went into full production in 1949.
Surely there are old photos of Soviet troops from the 1950s carrying early SKSs. If the blued bayonets appear in the photos when the weapons were new and had probably not yet been through a major refurbishment, that would seem to me to resolve this matter.
These are excellent points and facts that are hard to argue with, Boris.
What bugs me though is that blued bayonet is bigger and heavier and 'blued'. I admit my measurements are based on a sample of one but I read the same on the various forums, so for the sake of [present] argument let's assume this is the case. Soviet firearms have been always SUPER standardized and it makes zero sense for the Tula factory to produce two different types of bayonets for refurb and replacement. It is absolutely true that most of them are in top shape, why would they blue them for storage? Cosmoline has been always enough
What makes a lot of sense to me is that early production blade bayos were blued (as was Russian/Soviet tradition since the 19th century, including '49 spiker), then they quickly changed (smaller and cheaper without blueing to save costs and weight) and had leftover that could have been put on refurbs as needed. I think it is not unreasonable that it could have happened during late 49 - 1950 when so many changes were made. The '50 prevalence of blued bayos is also anecdotally confirmed by some Russian sources.
I'm the first to admit that this is purely a conjecture without much (any?) factual support but I'm a strong believer in Occam's razor and it just makes sense to me.
Also Russian sources separate blued 'shiny' and matte SKS blade bayos in addition to BBQ paint.
Again, this is Russian 'forum chat' but they are closer to the source...

This is a good suggestion. However there are some snags.
First contemporary photos of Soviet sks in service are extremely hard to come by. Dating them is also problematic. Not to mention the difficulty in distinguishing features that would allow us to put the date of manufacture into a specific range of years --the easiest feature to date being the the 45° vs Curved gas ports-- in grainy 75 year old black and white photos.
There are of course date specific features to enlisted uniforms which could be helpful. As well as photo enhancing software. Both of which are out of my wheelhouse or above my pay grade.
A 1950 Soviet armorers manual or service manual might be of help -- as bayonet color would be distinguishable in black and white hand drawn images.
Earliest service manual I have access to is dated 1951. But the blade bayonet images are inconclusive at best. Which also does not rule out (chromate gold).

Blued Shiny vs Matte? Or Shiny vs Matte?
I ask because the CIA text i posted an excerpt from above describes "chrome-plated" vs "rough finish". Which to me suggests simply the difference between a blade that has been highly polished and one that is not.
Blade bayonets on early prototype SKS-31 were bare steel.

Definitely blued shiny. Now that I looked at it closer they might be actually referring to the BBQ blued as matte.

Earlier I shared this 1949 sks sniper prototype with a dark bayonet suggesting that it might represent a brief transition from black spike to black blade bayonet. But I now see that the dark blade is an effect of the camera flash. Note how the center of the stock is washed out but the stock gets darker at the butt and fore end.
(https://i.ibb.co/QKXFqv6/4D6yiXl.jpg) (https://ibb.co/CHW5XKn)
Similarly there is a distinct border between the black handle and the blade. There is also some smudge type effect on the left side of the bayonet that strikes me as possible the reflection of an oily thumb print.

The blade bayo definitely looks dark but not blued. Could be part of the trial as a sniper rifle to darken the mitigate reflective glint.
The sniper prototype is the OMB-180, discussed along with other sks sniper variants here:

These are some good points. Which I have given a lot of consideration over several years.
I agree that standardization is a unmistakable trait for soviet standard issue small arms. The key phrase here being
issue small arms. Even as it went into full production in 1949, the sks45's phase out was already being planned. By 1955 the Soviets had ironed out all production issues surrounding design, and the AK was ready to go into full production. With sufficient quantities of AKs being produced, the SKS was no longer the standard issue small arm. As I see it, the sks45 was only ever a stop gap measure left in place until it could be replaced with robust production of the AK rifles. By 1954-55 the sks was no longer standard. As a result the standard for the bayonet was determined by individual storage facilities.
Coincidentally, it is exactly at this juncture in time that the Chinese start 'producing' their own exact copy of the SKS. We know for a fact that the first 2000+ Chinese guns were built on soviet receivers. And as late as 1958 there is irrefutable evidence that Chinese guns were still being built on surplus Soviet receivers. (I'll try and locate the thread: but running-man shared encountered a 3rd year/1958 Chinese sks and beneath the stock line it is literally covered in Soviet inspection stamp!!). 1958 is also when we see China's first aesthetic deviation from the Soviet design standard with the introduction of the side mounted stock sling swivel.
Regarding Cosmoline. It is an obvious way to protect against corrosion. But the Soviet rifles that ended up in the US weren't caked in cosmoline when they arrived-- like the mosins, and Toks , Albanian type56's, etc. Inspection of the Soviet stocks reveals they are completely devoid of grease. To me this suggests that they were dry when placed into ready storage. Without cosmoline protection, rifles put into long term ready storage would have required regular inspection and maintenance to prevent rust and to touch up or refinish flaking lacquer finishes. This also provides a really good explanation for the the crossbolt stamps-- the common pattern being one or two worn to barely visible stamps next to crisp highly visible stamps.
From what I've seen and read, I strongly believe that the 1956-58 carbines were built on scrubbed, soviet made barreled receivers. And the 60% drop in yearly production totals from 1959 through 1961 is evidence that Soviet supply of receivers dried up almost instantaneously at some point in that three year period.
Scouring the internet this morning I came across this image on pinterest.EDIT Phos32 pointed out to me that this is not a 90° port and I now agree. Appears to be a 90° gas port with a blade bayonet. It is however an issued rifle with bare white blade. No accompanying description and a google image search found no match for the image:

Rare color photo of Soviet sks in service. Soviet marines. Gas port looks 45° but it's very low resolution and given the angle of the photo it could be curved. Still, here we have a bare white bladed sks45 in actual service .
